Why is this so hard for you to understand? What is the rho
of the following?

source---50 ohm feedline---+---150 ohm feedline---load150

"Just the characteristic impedances" are given. You say you
can "calculate rho accurately" from just that. So prove your
statement. (load150 means the load is not equal to 150 ohms)

If you say rho = (150-50)/(150+50) then you are mistaken. If
Born and Wolf say rho = (150-50)/(150+50) then Born and Wolf
are mistaken. rho = Vref/Vfwd and, contrary to what you say,
there is *NOT* enough information given to calculate rho.
